Collaboration Teams - Members share responsibility for posting refined answers to the guided readings - succinct, relevant, clear, and with pictures or a video to compliment.
When contributing to the reading guide, follow these steps: 1) First complete the reading guide on your own from the chemistry unit page. 2) Write your response to a question in word and then copy it. Be sure to upload pictures and/or video for each question. 3) Click on the edit button and then go to the appropriate question and paste your answer below it.Sign your contribution with your first name and last initial and TEAM COLOR 4) Scroll to the very bottom and in the Optional comment box, place a summary of what you did and sign it (e.g. "I answered chp 26 question 3" - Tom S.) Then click Save.

1. Why is organic chemistry so important in the study of biology (include at least 3 reasons with pictures to support each)?
Pictures to extend examples
Organic chemistry is the study of structure, properties, composition, and reactions of hydrocarbons and their derivatives. 1. It is important because compounds can be synthesized in a laboratory and the structure of the compound can be analyzed by the elements within it.
2. Another reason for its importance is because it allows for testing with reactions. Different compounds can be tested with each other and reactions that occur and display certain results that can be useful.
3. Inventions are a true turnout of organic chemistry. Because of organic chemistry, things like petroleum and artificial rubbers were invented.

2. Why was the Urey-Miller experiment so important (try to place a diagram or picture here)?
Explination of importance in your own words
The experiment showed that organic compounds can be formed by combinding two inorganic compounds at the right conditions.
3. What is special about carbon that makes it the central atom in the chemistry of life (video or pictures)?
Nice collaboration
Carbon is the central atom in the chemistry of life for many reasons: One, it makes up about 25% of our bodies’: carbohydrates, lipids, proteins, and nucleic acids and 72% of it is water (so there’s only 3% of other things making up our body). Two, it can form single, double, triple and quadruple bonds. This is because of its 4e- valence shell. Also, it’s non-polar in water (when its bonded to Hydrogens—making it hydrophobic, which it usually is). And its stable—not too much attraction btw other molecules. ------ Brian N
Jackie, Sean i need help on this one so if you could try and change/alter it.
Brian, my answer was very similar to yours I think we talked about it in class at some point, but this is what I have: Carbon is special because it contains four valence electrons (in its outer shell). This allows carbon molecules to form many different types of bonds with other elements, thus causing carbon to be the backbone or support of many elements. –Jackie H. yellow team.
(The electrons in the second energy level are the valence electrons). --Jackie H yellow team.
4. Upload pictures to contrast the three types of isomers.
The "contrast" part needs to happen with your own words
Structural Mario
They differ in covalent partners.
Geometric Mario
They differ in arrangement about a double bond.
Enantiomers Mario
They differ in spatial arrangement around an asymmetric carbon, resulting in molecules that are mirror images.
5. Create a table below: For each functional group – upload a picture of the structure, name the compound, and note the functional properties –
A-D are great!
a. Hydroxyl
Structure
Name
Example
Properties
A hydrogen atom is bonded to an oxygen atom, which, in turn, is bonded to the carbon skeleton of the organic molecule.
Alchols (their names usually end in ol)
Ethanol, the alcohol in alcoholic beverages.
·Is polar as a result of the ectronegative oxygen atom drawing toward itself ·Attracts water molecules, helping dissolve organic compounds such as sugars
b. Carbonyl
Structure
Name
Example
Properties
the black atom signifies the carbon and the red, the oxygen molecule. In this example the two green atoms represent chlorine atoms attached to the carbonyl molecule
This consists of a carbon atom joined to an oxygen atom by a double bond.
Ketones if the carbonyl group is within a carbon skeleton.
Aldegydes if the carbonyl group is at the end of the carbon skeleton.
Aceone, the simplest ketone.
Propanal, an aldehyde.
·A ketone and an aldehyde may be structural isomers with different properties, as is the case for acetone and proanal.
c. Carboxyl
Structure
Name
Example
Properties
Carboxylic Acids (organic acids)
Acetic acid- sour taste of vinegar
·-acidic properties-source of hydrogen ions
-hydrogen ions dissociate reversibly due to polarity of covalent bond between H and O -In cells in ionic form called a carboxylate group

d. Amino
Structure
Name
Example
Properties
Amines
Glycine, Amino Acids
-acts as base- picks up protons from the surrounding solution -Ionized, with a charge of 1+ under cellular conditions

e. Sulfhydryl
What about us?!
Thiols. Two sulfhydrl groups can interact to help stabilize protein structure. Example: Ethanethiol.
f. Phosphate
Organic phosphates. Makes the molecule of which it is a part. An anion (negatively charged ion). Can transfer energy between organic molecules. Example: Glycerol phosphate.
